To aiZZ whom t may concer/a:

Be it known that I, RAYMOND O. Worms, a citizen of the United States, residin at Maplewood, in the countyV of Shelby and State of Ohio, havey invented, certain new and 'useful Improvements in Pumps, ofv

which the following isaspecification. ,p

VThis invention relates Y. in rgeneral to Vinternal ycombustion engines and Amore speits mounting in a desired cifically-to a pump which is constructed to facilitate the priming of the cylinders of an engine when necessary. H

Y One objectV of .this invention -isthe. producl tion of Va. manually operated pump wherein means are provided for collecting a charge of gas which is directed tothe cylinders of an engine. Y

Another object .of thisY invention is the upon a valve casing, this casing also communicating' with a source of liquid; fuel supply and-.also with the outer atmosphere, a communication ,being provided with Ya cut `production of .a pump, which is supported off, vwhereby when desired lthe cut o may Vbeoperated Vfor allowing the gas and air to be'y drawn .intoY the fpump whereupon this mixture may then be forced'through-suitable conduits to the priming device of the cylin- Vders of an engine.

Another- Object of this invention is 'the production of a pump which is simple and` compact in construction, thus facilitating tion?` and .under such conditions requiring only a mlnimum amount of space.

One practical form of construction and' assembly of the` present invention together with a slight modification thereof,` areV illus'- trated in the accompanying drawing, in wh1ch':-`

F igurel is a side elevation the pump,

the'dashsupporting thesame being shown in section and the several conduitslbeing broken away. H 4 i i Fig. 2 is Van'enlarged vertical section throughfthe device illustrated Vin Fig. 1, and 'Fig. 3. isfa' fragmentary side elevation of a sligdrtly 'modified form of the present inventijon'. Q c y 4 'Y In'the' preferred embodiment of the present-,invention about to be described,.5 indi- Cates in general Vthe valve, casing. lThis valve Acasing jcomprises the body 6 having plate 7 thereon whereby the pump maybe supportedv in a desired posi- Vtion upon the dash 8 extension 15.

of an automobile or other like vehicle.

The body 6 is provided with a horizontally extending cylindrical portion .9 having the tapering bore 10 extending therethrough as shown in Fig. 2. A reduced bore 11 communicates `with the vinner end of the tapering bore 10 and the socket 12 is formed in theoppositeside of the body 6 to communicate with the opposite end of the reduced bore 11.

The rotary valve 13 tapers from its outer end toward the inner end thereof to lit snugly within the taperingbore 10. This rotary valve has a shank 14 extending from its inner end and terminating in a threaded A spring 16 i'its within the washer 17 being retained by the nut 18. Accordingly the tension of the coil spring 16 will tend tok hold the rotary valve 13 firmly within the tapering bore 10L of the body 6 although permitting the valve 13 to rotate. For the purpose of rotating this valve there is provided a wing 19 thereon, this wing having different indicating legends on its opposite surfaces, such as the word gas or air as suggested by Figs. 1 and 3. also provided with grooves 20 and 21 for purposes to be hereinafter set forth.

.The body .6 *has` a depending lneck 22 in which there is formed a threaded socket 23. The passage 24 leads from the inner end of the threaded socket 23to the tapering bore 10. An air lpassage 25Yis formed in the body 6 and extends substantially parallel to the passage 24 and also communicates with the tapering bore 10.

The elbow 26 is screwed into the socket 23 andcommunicates with the passage 24. This elbow 26 is connectedrby the coupling 27 with the tube 28Vleading to the liquid fuel supply. A recess 29 communicates with the tapering bore 10 and has the passagel 3() leading therefrom to communicate with the pocket 31 in which is carried the coil spring 32 and the ball valve 33. The bearing of the spring 32 `upon the ball valve 33 permits passage through the pocket 31 in one direction although preventing repassing through the pocket, thus constituting. a check valve.

The internally threaded supporting flange 34 is carried on the body 6 and the barrel 35 is screwed into engagement with this vicev and thus. increase the unobstructed' space adjacent the dash and also minimia" flange 34. A piston 36 which may be of any desired construction is carried within the barrel 35 and Vis mounted upon the threaded end of the piston rod 37. It should be noted that the inner end of the rod 37 is tapered as shown in 38 for purposes to be communicate with the interior of the barrel 35. The valved nipple 45 is provided with a suitable coupling 46 for attaching thesev-y eral'conduits 47 thereto, these conduits in turn being suitably connected to the cylin` ders of an engine.

As will be apparent from an inspection ofFig. 3 lthe modified'form of the invention is so constructed as to have the major Y portion of the pump carried upon the for` Vward side of the dash and nearer to the engine so that the projecting parts will be those necessary to the operationof the deing* possibility of injury to the deviceby accidental striking of the same.

The valve casing 5 is provided with a hollow cylindrical portion 9 in which the rotary valve 13 is mounted and retained by suitable retaining means 18. The neck 22 has a connection 48 for securing the tube 28 thereto. The stem 49 leads from the rotary valve 13 and passes through the dash engine.

the invention it should also be noted that a 8 to support the wing 19. Thus it will .be seen that the wing19 may be gripped and turned for shifting or turning the valve 13.

The barrel 35 is connected to the valve Vcasing 5 and has a cap 39 mounted upon its opposite end. Thiseap 39 is provided with an enlarged iange 50secured as indicated at 51 upon the dash 8. The head 41 is carried by the piston rod 42 in the manner shown in Fig. 2.

The valve-casing 5 is'provided with a passage 44 leading to the neck 43 to which the valve coupling 45 is secured andin turn is connected inthe manner illustrated in the preferred form to the cylinders of the In connection with this form of checlr valve 33 is provided an airrpassage 25 and a gaspassage 24.

Operation-XV hen it is desired to provide the engine with a highly combustible mixture, the wing 19 is turned tobring the groove 21 of the rotary valve into communi,

cation with'the air passage 25. The head 41 of the piston rod 37 is pulled away from the cap, thus retracting the piston 36 from the innerV end of the barrel 35. This action will cause a suction withinthe barrel and as the valved nipple 45 will prevent a back flow into the bar-rel, this suction will remove the ball valve 33 Jfrom its seat and thus draw air throughthepassage 25 intothe recess 29 and then into :the passage 30 `and the pocket 31 into the barrel 35. When it is desired to draw gas into the barrel 35 it will be -easily understood that the rotary valve is operated so as to place theV groove 20 into communication with the pocket 29 and the passage 24'. Piston lrods 37 have the indicating lines 42 to 'allow the operator to determinehowfar the rod should be drawn to cause the valve to'receivel a desired quan-l tity of either'` air` or Vgas as may be desired. As soon as outward movement 'ofY the'piston rod is stopped, it isobvious that the ball valve 33 will return to its seated position and thus constitute a check valve.

Althoughthe operation of the preferredA form of the invention has been set forth, it is obvious that the operation of the .modied form is identically similar. The difference between the two devices, is, as above Ypointed out, the 'manner in which they are supported. A' Although the barrel 375 is carried upon the rearwardv side of the dash in the preferred form it is seen that instead of i aving the flange 34 thereofnslanted up?V wardly at an Vangle it may be turned in a vertical manner and thus cause the barrel to extend horizontally while by placing the valve casing yon the forward side ofthe dash 8 the rotary'valve may be easily operated by the stem 49.

The foregoing description andaccoinpanying drawingsphavereference to j what might `be considered to be the preferred or approvedform foi' my'finvention. I'Udesire'- it to be understood that I may makesuch changes 'in the construction, combination and arrangement of parts,'material s, dimensions, et cetera, as may prove expedient and fall within thescope of the lappended-claims. rHaving thus fully described my invention what I claim as new and'desire to secure Letters Patent, is ;V i i Y i. in a device ofthe ciassaeserbaae combination'of a. valve casing', said casinghaving an air passage anda gas'fpassage communicating with recess, pump means connected` toA said casing, saidfcasing :also
